Switching the menu icon to a cross icon when clicked in Reactjs - a step-by-step guide

I've been trying to develop a website with ReactJS and implement a feature where the menu icon toggles when clicked using an onClick event in ReactJS. However, it doesn't seem to be working as expected. I'm not getting any errors, but the icon isn't toggling. Any ideas on how to correct this?

import React, { Component } from 'react';
import './Sidebar1.css'

class Sidebar1 extends React.Component {
        toggleIcon() {
            // code to toggle the icon
        }

        render() {

            return (
                <div className="sidebar1">
                    <div className="menuIconStyle">
                        <a href="#" onClick={this.toggleIcon}>
                            <i className="fas fa-bars"></i>
                        </a>
                    </div>
                </div>
            );
        }
}
export default Sidebar1   

Answer №1

  • Declare a boolean variable to track the toggle state e.g.
    [isOpen, setIsOpen] = React.useState(false)
  • Update the class when the button is clicked e.g.
    <i className={`fas ${isOpen ? "fa-times" : "fa-bars"}`}>
  • Use setIsOpen() within the button's onClick event handler
